U.S. Air Force Senior Airman Timothy McAlister and fellow Tactical Air Control Party specialists flip a 230-pound tractor tire across the final lap of the TACP Association 24 Hour Run Challenge at the 182nd Airlift Wing in Peoria, Ill., March 29, 2013. Sixty-two runners ran 161.75 miles around the installation over the course of 24 hours and raised more than $8,200 in support of the TACP community and their families. The 182nd team also ran in remembrance of Staff Sgt. Jacob Frazier, a member of the Peoria-based 169th Air Support Operations Squadron who was killed in action near Geresk, Afghanistan, exactly 10 years earlier. (U.S. Air Force photo by Staff Sgt.
